Abstract: A method and system for networking a plurality of appliances. The method and system include providing an appliance on a network, controlling operation of the appliance with a microcontroller, storing on a memory coupled with the microcontroller, computer executable instructions for operating the appliance, sensing the operation of the appliance, displaying information regarding the operation of the appliance, and communicating the operational data on a network. Network connectivity includes communication directly with a network, and with another appliance. A host system is connected to the network and adapted to receive the usage data and to transmit data to the appliance to influence operation of the appliance.

Abstract: An electrically operated thermally responsive valve having a bimetal operator arm heated by an electrical resistance heater for deflection to move a resilient poppet between an open and closed position on a valve seat for controlling flow to the valve outlet port. The base or active portion of the bimetal arm is formed of a first bimetal material with linear deflection properties up to 700.degree. F. for valve operation. The outboard end or compensator portion of the bimetal arm is formed of a second bimetal material having linear deflection properties up to 300.degree. F. for ambient compensation, but very low deflection properties at valve heater temperatures in the range 300.degree. F.-700.degree. F. for minimizing overcompensation from heating of the outboard portion due to heat transfer from the active portion.

Abstract: A wire mesh filter screen has a flat disc shape and is seated on a flat bottom counterbore in a threaded fitting. A circular knife edged punch pierces a ring of material from the counterbore wall surrounding the disc periphery. A second flat punch axially deforms the ring over the disc periphery to securely retain the screen in the fitting.
